Download Free 3D Model Lightpainting Interval Exposure Tool 3D Print Model

Summary
This is a tool designed to be used in long exposures. It spins a disc with open segments in front of a camera lens to interrupt a long exposure in intervals. This creates a unique look in light trails and any other technique used in lightpainting.
This tool uses a geared 12V dc motor with around 720RPM with a standard PWM controller.
The controller potentiometer knob is mounted outside the box along with a power plug and a switch for power. The discs are separated to be printable but need at leas 300×200 print area.
The slit disc right is actually a little wrong, it should have been mirrored. I realized this after i printed and glued them together, but left them as they are because this creates a slight irregularity that adds character and makes the pattern look less artificial.
Example images show which type of disc created which type of effect.
Detailed instruction for this technique will be published soon and I will add a link here once they are.
